Good luck with the hub. They can be really stubborn on AA's - maybe because of the above mentioned reason and maybe also because of the larger axle diameter and therefore the larger surface area the hub can be stuck to.
I had one like that and thought I could remove it with a knock-off type puller. I banged on that until I thought I was going to go mental and it wouldn't so much as budge. Even heating it up with an oxy/acetylene torch didn't help. Then I got a vintage puller that threads onto the hub where the hub cap fits. The puller has a cut in the side and a bolt that allows you to clamp it to those threads. I put it on, clamped it tight, screwed the center bolt down tight but not so tight that you'd strip either the threads for the bolt in the puller or on the hub. Then I hit it with an 8 pound hammer a couple of times and off came the hub. I was amazed.
Since you've tried several different wheel pullers already, maybe this won't work as well for you or maybe I was just lucky. If you can figure a way to keep the axle nut on but loose and put a hub puller on AND drive it around the block a few times, maybe the combination of all would finally work. Be sure to let us know how you make out in case we are faced with something like the in the future.
